Mosquito

anatomy

The mosquito's body, like any other insect, is divided into 3 parts:
head,
thorax and
abdomen.

They have 6 legs,
1 pair of antennae,
1 pair of maxillary palps and
2 compound eyes.

 

Although Mosquitoes
have relatively small
wings they have scales
on them to reduce
friction and help them
fly.

 

 

 

 

mosquito

Both male and female mosquitoes have a proboscis which is a feeding tube, but only the female feeds on blood ( nectar if she's hungry). Males feed only on nectar.

proboscis key

 

The most important part of the female is her proboscis.
The proboscis is a serrated elongated mouth part, protected by her scaly lower lip which stretches to cover it.
The lower lip is called the labium. The upper lip is called the labrum.The labium ends in 2 hairy lobes called the labella.
The proboscis is made up of 6 parts, 2 pairs of flexible cutters surrounding a pair of very thin tubes;
one very sharp one that pierces the skin and sucks blood, the other injects saliva.

It takes the female about 50 seconds to insert her proboscis into the skin. It is serrated to decrease nerve stimulation. She feeds for about 2 and half minutes.
When she has pierced the skin she injects a small amount of saliva which contains a chemical which stops the blood clotting (anticoagulant). It is the foreign proteins in the saliva that make us itch.

Proboscis
"Sensilla on the maxillary palps of females contain an olfactory receptor neuron which produces a phasic-tonic pattern of action potential responce to low concentration (150-300 ppm) of carbon dioxide a stimulus known to be involoved with host-seeking benavior. These receptor neurons respond reliably to small increments in carbon dioxide concentration (50 ppm) likely to occur in nature." (Robert OConnell, Ph.D.)

If you slap him, you get hurt.
